...but don't expect to be able to load it WITH 50 lbs an not have it fail often. Find the definition of "Factor of safety" and use maybe 10 here. Also, compare that number with McMaster's spec on steel #35.

I know that VeX chain looks pretty beefy but one of the other Pudue area teams (1747-HBR) used plastic chain in the past and it really depends on how you use it. One year they had no problem but they were spinning a turret on it (hardly any load) but another year they broke it alot because they had some stress on it. Obviously it's nice because of the weight reduction but just keep in mind what sorts of things you intend on doing. Hope this can be helpful.
